To train for a big roce. Chelsea a runs the some route each weekday morning from-her house. She runs north for 0.75 mie and west for 1 mile. Then, she runs o straight-line home. What is the total distance Chelsea will run each week?

Total distance covered on each week = 5 * 3 = 15 miles

Step-by-step explanation:

She runs north for 0.75 miles and west for 1 miles. Then she runs a straight line home. The illustration will form a right angled triangle. The straight line she runs home will be the hypotenuse of the triangle.

Using Pythagoras's formula one can calculate the hypotenuse.

c² = a² + b²

c² = 0.75² + 1²

c² = 0.5625 + 1

c² = 1.5625

c = √1.5625

c = 1.25 miles

Total distance covered each weekday = 1.25 + 0.75 + 1 = 3 miles

Total distance covered on each week = 5 * 3 = 15 miles

Note that weekdays are Monday to Friday

She runs 3.50 miles each week.

0.75 + 1 = 1.75

1.75 + 1.75 = 3.50
